We all have that special someone in our lives who keeps us on track when we want to lose our cool. Well think of the MRP G4 Aluminum single-chainring guide as that special someone for your chain and chainring. Building upon MRP's famous G3 guide, the G4 upgrades its upper guide to utilize a softer durometer TPU material on the interior walls and ceiling to silence drivetrain chatter.
Sticking to the G series' World Cup proven design, the G4 Aluminum Chainring Guide combines the skid plate and lower guide into one solid piece that can take hit after hit. This integrated skid unit protects important drivetrain parts like your chainrings from being torn apart by hostile rocks and roots.
The MRP G4 Chainring Guide also features MRP's Swingset hardware design which allows you to easily change cranksets without having to remove the guide. The included pulley and G-slide slider block ensures proper chain wrap for quiet, dependable operation in muddy and damp conditions - an important factor when flying through a rutted and rooted section of the trail. The MRP G4 Aluminum will keep both you and your chain on the right track.

I race Downhill in the NW Cup and this is one of the best chain guides I have ever ran. I love that it only goes up to a 36T sprocket as that is the most common size for a downhill bike so it makes the bash guard nice and short just long enough to stick down past the chain how it should. This gives you great ground clearance. This chain guide also comes with a slider block so you can remove the pulley and just run a plastic slider. This is a great feature for riding in the mud or just anytime really. I run it all the time. I have had E13 chain guides in the past but love the one piece design on the bottom. This makes it both stronger and easier to put the chain on and off. I used to break at least 2 pullley bodies on the E13 ever year. Overall a great guide and I would buy it again.
